Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574474, here are decompositions:

7 + 31574467 = 31574474
31 + 31574443 = 31574474
37 + 31574437 = 31574474
241 + 31574233 = 31574474
271 + 31574203 = 31574474
367 + 31574107 = 31574474
433 + 31574041 = 31574474
643 + 31573831 = 31574474

Showing the first eight; more decompositions exist.
